Hello, I've been using Firefox for almost two decades now. I've never had issues with it until recently. I'm at my wits end here and considering switching to Chrome. I don't want to, but Firefox is basically unusable for me now. I thought I'd ask here first and see if anyone can help.

Issues started after I switched from Win7 to Win10 last year. My wife and I are both running Win10 with Avast antivirus and Firefox works fine on her PC (a basic off the shelf HP desktop). Mine is a home built gaming PC. Specs: Asus Z87+ mb, Intel 4790k 4Ghz processor, 32 GB ram, Nvidia Geforce GTX 1050 Ti 4GB graphics card, 6 TB internal storage.

Firefox began running extremely slow and wouldn't load pages sometimes. I found there was an update available that hadn't automatically downloaded, so I applied that (it's been updated about 3 more times since then), but it still ran slow. I checked troubleshooting articles here, tried turning off hardware acceleration in performance settings and it suddenly seemed to start working again. I found my GPU driver was way out of date...I didn't have the correct Invidia app installed to automatically update the driver after I installed Win10, so I corrected that. That seemed to help for a bit...some sites like Facebook and YouTube started working again, but some still were slow or wouldn't load at all (primarily online merchants like Wayfair, Amazon, etc.).

It's been progressively getting worse, to the point most sites don't load again. If I restart the browser in troubleshoot mode, some sites will load again and others won't. I don't understand why though, as I have no extensions or anything else installed. I have tried turning off DNS, turning off hardware acceleration again, disabling the shield in the address bar, turning off the antivirus firewall, adding Firefox to the allowed programs in Avast, turning proxy off, clearing cookies and cache, and doing a refresh of Firefox. Nothing has worked. Any ideas of what the issue might be? I really don't want to go back to using Chrome or worse yet...Edge <shudders>.

I can no longer connect to Firefox VPN even though I still have VPN data/allowance left. It says that local laws and restrictions limit VPN use. What is the solution?

Hello,

My Firefox dashboard looks very different. I like a darkview mode and it won't connect to dark view mode. Also, for each website I visit........it looks different and connection is questioning my access each time. I've compare this to my laptop and the same website looks different.

Please help. In fact, right now, this page won't allow me to select the option to email me when someone answers the thread. My email address is [redacted email from public community support forum]

Thank you in advance.

WebGl2 stopped working after a my Mac Froze up (required reboot)

I tried this ... " Enter about:config in the address bar and set webgl.enable-webgl2 to true." Did not help.

I unistalled Firefox and re-downloaded. Still same issue.

I then tried to adjust the "Use recommended performance settings" (recommendation from Firefox). still not working.

I tried using Safari, and it works fine.

Any help appreciated

Until just a few days ago, I was able to use the Mozilla VPN, but now I can no longer use it; when I click to connect, it displays error {Local laws and restrictions limite where you can use VPN}.

Prior to this, I was able to use the VPN without any issues, and I have only used a few gigabytes of data.

the vpn is free... the limit is 50gb per month

once that is reached  until the month resets the VPN is just not available   is that correct?    thanks 🙏

Dear Mozilla Team,

I am a long-time, dedicated user of Firefox. Recently, my workflow has shifted heavily toward modern, resource-intensive web applications (such as large, stateful AI chat platforms, complex dashboards, and heavy documentation tools) that handle massive amounts of text and DOM elements over extended sessions.

While Firefox’s multi-process architecture is generally robust, power users often have to resort to tweaking hidden settings in about:config (such as adjusting process counts) to prevent performance degradation, memory management friction, or sluggish re-rendering during heavy, long-running tasks.

It would be fantastic to see more accessible, user-facing performance profiles or advanced resource-management options directly in the Firefox settings—for instance, a dedicated "High-Performance" or "Power User" mode for heavy web apps. This would allow users with high-end hardware (such as 32GB+ RAM systems) to explicitly allocate more resources and processing power to specific tabs or workloads without compromising the stability of the rest of the browser.

Thank you for continuing to build such an open, customizable, and user-focused browser!

Best regards, Thomas Prigl

Hi, I’m having a problem when I turn off the screen in Windows 11 26H2. The latest version of Firefox minimises the window to a small window, even though it was in full-screen mode before the screen went to sleep.

Following a windows 11 update some weeks ago on my Windows 11 Dell XPS 15 laptop, Thunderbird failed to connect to the internet. I have tried various "fixes" using Google AI but none has provided a permanent solution. I can sometimes get it to run by repeat clicking or by restarting but this only works on a hit or miss basis so can you help find a permanent solution?

I keep getting a pop up when opening my mail that reads, "The folder on inbox (then gives my email address) could not be compacted because writing to folder failed. Verify that you have enough disk space and that you have write privileges to the file system and then try again".

I don't understand!!!

for no reason get this message , just go OK says " Cannot be compacted because another operation is occurring" see attached It also does it for other folders & the like Am I accidentally hitting a keyboard combo or button that does that? or just random?

thanks

I'm talking about Firefox version 156.0 (64-bit)??? So since the last Windows 10 security update Firefox just wouldn't start anymore. I had two or three automatic refreshments of Firefox but even that didn't do the trick anymore in the end. Then there was a secundary Windows 10 update and I got everything running smoothly again for two days, and now today there was a Firefox update and the whole trouble started again. Even some sites wouldn't work anymore (outlook, DeepL) or I couldn't login anymore. I'll try going back to a previous version ...

Microsoft seems to have interfered with my computer. I have been using it for 10 years using Mozilla Firefox with no problems. Now all my own documents have been frozen and I am unable to make any alterations or continuation of text. I am desperately worried. I am 83 years old and started using computers relatively late in life. I am a complete 'generational novice'. It seems as if Microsoft has had some input. Please help
